OptionalCUDAGuard

[FuzhiYang]

Hi Haotian,

In the recent commit, "OptionalCUDAGuard" is added in mmdet3d/ops/bev_pool/src/bev_pool.cpp. I just wonder what is the purpose of this module?
I built the code in the old version (without OptionalCUDAGuard). Will this cause some potential errors?

Thanks,
Fuzhi

Hi Fuzhi,

This will not cause potential errors if you are not debugging the single BEV pooling op. OptionalCUDAGuard is related to the discussions in this issue.

Best,
Haotian

No problem. I'm closing this issue temporarily because the issue is resolved.
